Descrição: The effect of hen egg weight in the VEDETTE hybrid was evaluated with respect to the course and results of hatching; the interrelationships were also assessed. In the laying period (in the 28th, 40th and 52nd weeks of age) a trial involved hatching eggs (n=1 120 eggs) of various weight divided into groups (20 groups, 56 eggs per group) and it was aimed at determination of embryonic mortality until day 14, between days 14 and 18 and during hatching, as well as of hatchability of set and fertilized eggs. The fertility rate of eggs was found to be in a negative relationship to egg weight (r=-0.236). The relationships between egg weight and embryonic mortality until day 14 was r=0.464, mortality between days 14 and 18 r=-0.154 and during hatching r=0.456. The relationship of hatchability of eggs set into an incubator to their weight were described by the coefficient r=0.544 and those of hatchability of fertilized eggs to their weight by the coefficient r=-0.463.
